Emergency authorities in Victoria say favourable weather conditions are likely to assist firefighting efforts over the next few days.

Cool weather has reduced the risk to towns threatened by fires in Gippsland and the northern Alpine region.

The blazes are yet to be contained but are no longer threatening any towns.

But Andrew Benne, the state commander for the Department of Sustainability and Environment, says a run of hot weather could cause the fires to flare up again.

"If we have hot, dry weather return and those fires are still active, there is a very real chance that they could escape control lines," he said.

"So people need to remain conscious of what's happening in their local area."

Mr Bennet says overnight thunderstorms did not hamper firefighting efforts at Harrietville, in the northern Alpine region, and Aberfeldy in Gippsland.

"Those two particular fires only really received a couple of millimetres of rain," Mr Bennet said.

"The Bureau of Meteorology is predicting a few more storm cells through later today and they're informing us the band of storm activity that's in southern Queensland at the moment will move down the coast so we're likely to see a few more showers later this week."
